Introduction
CubeSats are miniaturized satellites that have become increasingly popular for space exploration and scientific research due to their small size, cost-effectiveness, and modular design. This project focuses specifically on the electrical aspects of a CubeSat, excluding any mechanical components.
The key objectives of this project include:
-
Power Management: Efficiently manage power resources to ensure the CubeSat's continuous operation in space.
-
Communication Systems: Implement reliable communication protocols for data transmission between the CubeSat and ground control.
-
Sensor Integration: Integrate and interface various sensors to gather data for scientific or mission-specific purposes.
-
Onboard Computer Systems: Develop the necessary software for the CubeSat's onboard computer to execute mission tasks and handle data.
-
Fault Tolerance: Implement mechanisms to handle errors and faults to ensure the CubeSat's robustness in harsh space environments.

Questions
How big is the Power System PCB?
It measures 90 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power System use?
50 parts, built around the TPS563201DDCT, INA226AIDGSR, DFE2016CKA-2R2M=P2 and M22-6003005. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Power System KiCad files?
From the Lifearafter/CASE repository on GitHub, at the commit this page was made from: the board is Schematics/Power_System/Power_System.kicad_pcb and its schematic Schematics/Comms_System/Amplifier_Array.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power System design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
